Upcoming LiDAR Training Workshop led by Dr. Michael Scott and Logan Hall

August 4, 2016 by ESRGC

Working with Topographic LiDAR

This workshop is designed to provide ArcGIS users with an introductory understanding of their topographic LiDAR data. Participants will begin with exploring and extracting a sample of data from our REST services page to be used with the hands-on portion of this workshop. Exploring the toolsets within ArcGIS for Desktop, participants will learn how to reclassify their data, create suitability maps, generate contour lines and build watersheds. Users will also create stream networks and generate flood depth grids. Throughout the hands-on portion of this workshop we will learn how to store and manage our topographic data, and how to automate processes in ArcGIS.
Participants are encouraged to bring a personal storage device should they wish to retain the models and outputs from this course.

ESRGC Completes Coastal Resiliency Assessment for the Deal Island Peninsula

July 25, 2016 by ESRGC

The ESRGC’s Brett Dobelstein along with Dr. Michael Scott has finished the flood vulnerability study for the Deal Island Peninsula Project’s Integrated Coastal Resiliency Assessment (ICRA).  The ESRGC worked alongside over 50 stakeholders from community, state, and federal organizations to assess the resilience of the Deal Island Peninsula.  The Deal Island Peninsula is located along the eastern side of the Chesapeake Bay and consists primarily of low-lying wetlands.  With an average elevation of only three feet, the Deal Island Peninsula is subject to flooding and erosion, which are expected to worsen due to the effects of climate change.  The overall goal of the ICRA is to increase the resilience of communities and habitats of the Deal Island Peninsula to the growing risks of coastal storms, sea-level change, flooding, erosion and saltwater intrusion.

The Integrated Coastal Resiliency Assessment will have three phases that will be completed using a collaboration between the scientific community and local expertise.  Phase One of the ICRA looks to determine the assessment of vulnerability based on multiple potential flooding scenarios.  Brett used multiple data sources and FEMA’s HAZUS-MH software to model the flood and damage coefficient in order to estimate for a variety of scenarios (years 2015, 2020, 2030, 2040, and 2050; various tides; 10%-, 4%-, 2%-, 1%-, and .2%- chance floods.)  Sea-level change values from the U.S. Army Corps of Engineers (USACE) provided the future base water levels.  The FEMA Flood Insurance Study provided projected water levels during annual chance flood events.  Based on this assessment the community and project partners have highlighted five areas representative of the Deal Island Peninsula to focus on in Phase Two.  Phase Two will identify, prioritize, and target restoration and adaptive strategies to implement for each focus area.  Phase Three will select and prioritize the projects identified in Phase Two along with pursuing funding for their implementation.

For more information on the project, and to view the selected focus areas in greater detail you can visit: http://www.dealislandmarshandcommunityproject.org//#!icra/c1kze

 

These selected areas are a combination between marsh and community dominant locations.

Baltimore County and the Town of Princess Anne formally adopt their Critical Area maps

November 6, 2015 by ESRGC

The Critical Area Mapping Update project is tasked with providing a seamless and consistent digitally accessible map of Maryland’s Critical Areas. Through a combined effort from Salisbury University, the Eastern Shore Regional GIS Cooperative (ESRGC), the Critical Area Commission (CAC), Maryland’s Department of Natural Resources (DNR), and the Department of Information Technology (DoIT) there are now 5 jurisdictions with formally adopted Critical Area Maps. Previous counties that have completed the approval process include; Talbot and Prince Georges.  In addition to these counties, the Town of Snow Hill has chosen to update and approve their Critical Area maps before Worcester County.

For the Critical Area Mapping Update project the ESRGC uses multiple datasets to digitize the shoreline and edge of tidal wetlands. Once the line work is completed the 1000ft Critical Area boundary is generated. Throughout the process there are numerous reviews with all stakeholders involved, including public information meetings where citizens can gain more information about potential map changes.

Baltimore County was one of the two pilot counties for this Critical Area mapping project and after years of review and hard work they have officially adopted the maps created by the ESRGC. The Town of Princess Anne has also adopted their own Critical Area map prior to the approval of Somerset County.  All of the formally adopted counties will be placed on the Maryland iMap site. The finalized Critical Area boundary maps along with other counties in the process can be viewed here: (http://webmaps.esrgc.org/cbca/desktop/Map)  You can also use this web map to determine if your property is  located in the Critical Area as long as your county is in the “Working draft map” stage.

If you have more questions regarding the mapping project or to better understand the Critical Area you can visit the Critical Area Commission’s website (http://www.dnr.state.md.us/criticalarea/)

ESRGC Partners with Maryland to Launch Community Investment Tax Credit Program Dashboard

October 20, 2015 by ESRGC

The ESRGC, through Maryland Department of Information Technology (DoIT), and in collaboration with Maryland Department of Housing and Community Development (DHCD), is pleased to announce the release of DHCD’s Community Investment Tax Credit (CITC) Dashboard. The forward-facing application showcase’s Maryland’s initiative to better connect potential donors and nonprofit organizations, furthering investment in Priority Funding Areas (PFA). The CITC Dashboard helps donors target charitable contributions to Maryland nonprofits in the community of their choosing. Did we mention supporters receive proportionate tax credits on their donations!

The CITC dashboard allows users to explore the spatial distribution of nonprofit organizations across the state and to compare the amount of tax credits available, amount of tax credits used, and the amount of tax credits awarded in each county and region. Potential donors interested in locating a particular type of organization can quickly filter the data by program or project type. A keyword search of the tabular data is available for users interested in tax credit information for a specific organization.

This cross-platform dashboard was built using open source technologies and open data: Node.js and Socrata 2.0. Node.js supports many modern browsers with responsive design. Using Socrata as the dashboard database enables DHCD to maintain not only the dashboard data but many other elements including images and text found throughout the website. Socrata also provides real-time updates to the dashboard.

To get an idea of how the dashboard works in more detail, please feel free to navigate to the link provided below. All you need is an internet connection and any web browsing enabled device.

ESRGC Technical Director presents at International Conference of Open Source GIS in Seoul, Korea

October 1, 2015 by ESRGC

Wearing a Salisbury University baseball jersey, Dr. Art Lembo presented a paper at the International Conference on Free and Open Source Software for GIS (FOSS4G) in Seoul, Korea.   The paper, Integrating Open Source GIS Software in Undergraduate Curriculum, Research, and Outreach – Recent Experiences at Salisbury University, focused on Salisbury University’s use of open source GIS in course curriculum, research activities, and outreach activities.

Lembo discussed the use of FOSS4G software in Department’s curriculum including the use of spatial SQL and PostGIS in GEOG 435 – GIS Programming, Quantum GIS in GEOG 419 – Advanced GIS, and CartoDB in GEOG 321 – Cartographic Visualization.  Lembo also presented his recent research activities using open source technology with Hadoop for the National Science Foundation, and the use of node.js and leaflet.js for the Kellogg Foundation and the Sea Gull Century.  He concluded his talk demonstrating the Eastern Shore Regional GIS Center’s (ESRGC) use of open source technology for the various geo dashboards created for Federal, State, and Local government clients.

Lembo stated that the growth of open source geospatial software has reached a level where its use can no longer be ignored, especially by academic institutions that offer degrees with a concentration in GIScience.  To that end, Salisbury University will continue to introduce leading edge open source technology into its curriculum, research, and outreach activities.

 

Dr. Stuart Hamilton, a Salisbury University Geography and Geosciences Professor and Affiliated Researcher with the ESRGC, along with Undergraduate and Graduate Students has Completed an International Project Researching Indonesian Mangrove Forest Losses

Mapping Indonesia Mangrove Forest Losses

Mapping Indonesia Mangrove Forest Losses

Salisbury University’s Eastern Shore Regional GIS Cooperative (ESRGC) has just completed an international project, funded by the Gordon and Betty Moore Foundation, to monitor mangrove loss in Indonesia. SU undergraduate and graduate students identified changes, since 2000, in the mangrove forest inventory of the archipelago in Southeast Asia. Containing just under one-third of mangroves globally, Indonesia is the most important frontier for mangrove conservation efforts. Mangroves are an effective tool in mitigating global climate change, as they contain one of the largest forest “carbon sinks” per hectare worldwide. Additionally, they help power globally significant fisheries, protect coastlines during storm events, and provide bordering communities with food security and income opportunities.

Indonesia has lost 3.11% of its mangrove forest area (Hamilton and Casey 2014) since 2000. This is substantially higher than the 1.97% global average. This is problematic as Indonesia contains approximately 28% of the world’s mangrove forest. To put this in perspective, Indonesia’s 21st Century mangrove loss is more mangrove forest than actually exists in all but 20 of the top 100 mangrove-holding nations. Earlier research indicates aquaculture, agriculture, and urbanization as reasons for mangrove losses in Indonesia pre-2000, but post-2000 the reasons for the continued mangrove loss remained opaque until this study.

Results indicate that between 2000 and 2012, Indonesia is responsible for 45% of global mangrove losses and aquaculture is responsible for approximately 70.86% +- 9.65% of these mangrove losses. Therefore, by tackling mangrove to shrimp conversion in Indonesia the environmental community would be addressing a little under one-third of global mangrove losses. Indeed, by focusing resources still further on specific estuaries in Kalimantan this would account for the majority of Indonesian mangrove losses and mangrove forest to aquaculture conversion.

Projects such as this not only help undergraduate and graduate students become involved in the process of research, but actually contribute real meaningful findings to institutions such as the Intergovernmental Panel on Climate Change that are at the forefront of research into the driving mechanisms behind global warming. As part SU’s commitment to undergraduate research, this type of project allows students to apply cross-curricular components of their SU education to address real-world environmental problems.

Upcoming Workshop at UCGIS led by Dr. Arthur Lembo, SpatialSQL: A Language for Geographers

May 19, 2015 by ESRGC

Dr. Arthur Lembo, Technical Director for the ESRGC, will be giving a workshop entitled SpatialSQL: A Language for Geographers at the University Consortium of GIS (UCGIS) Annual Conference on May 27th in Alexandria Virginia.

The workshop is geared toward geographers with minimal or moderate computer skills, and will emphasize the power of spatial SQL by showing the principles behind spatial SQL, and how very simple, English-like SQL statements can solve standard data manipulation tasks for statistical analysis, data aggregation, and relationships.

This will be a hands-on workshop where the students will work alongside the instructor to actually write spatial SQL queries using a real world data set. Attendees should bring their laptop so they can install a minimalistic GIS tool that uses spatial SQL. At the end of the workshop, attendees will appreciate this easy to use and underutilized toolset at their disposal, and recognize how simple it is to leverage the power of SQL for GIS tasks.

Information about the workshop can be found at the UCGIS website: http://ucgis.org/event-item/workshops-0
